The main post-harvest concern is with the processing and storage, which plays a fundamental role, since they seek to guarantee the quality of the product that comes from the field. The storage process is the activity that stores and conserves the grains, aiming to guarantee the quality of the product regardless of the time it is kept in storage (BROOKER, 1992 apud LIMA, 2013). The objective of this work is to monitor the classification, temperature and humidity of soybeans at the Coopergrãos Cooperative, located in Nova Andradina – MS, and how these variables interfere with the quality and longevity of grains stored in silos. The temperatures were obtained through thermometry performed with the Thermo Collector MOD. V5 FOCKINK, where weekly temperatures during the months of May, June and July were monitored for each cable and its respective sensors. During this monitoring period, two samples of soybean grains were collected on different days in June to gauge moisture. The samples were withdrawn with the interval of 20 minutes to representatively express the material present in the silo, and were collected at the end of the conveyor belt. There was no proliferation of microorganisms or insect pests, where the grain mass did not present favorable humidity and the temperature was below the optimum for its proliferation. In the classification, we found the total number of defects above the allowed for soybean, but it was framed as Out of Type which does not prevent the sale of grains for other uses in the commercialization.
